Abstract:

Cloud point extraction (CPE) utilizing non-ionic surfactant TX114 was carried out to separate and concentrate di (2-ethyl hexyl) phosphoric acid (D2EHPA) in its dilute aqueous solution.The CPE process was facilitated at 45℃.The influence of TX114 concentration, D2EHPA concentration and solution acidity on the extraction efficiency was studied.The results showed that extraction efficiency increased with decreasing TX114 concentration and increasing D2EHPA concentration.Such unusual extraction behavior might be the result of the reverse-micelle coacervate phase, solublizing D2EHPA on the surface of micelle, and the influence of D2EHPA on the cloud point of TX114.
